This standard specifies the thread form, steel rods and short rods, fiber-reinforced plastic FRP rods and short rods, sinker bars, polished rods, couplings and reducers, thread gauges, pumping tees, stuffing boxes, polished rod clamps, measurement equipment calibration, standard methods of mechanical property testing, and design requirements and guidelines for polished rod liners.
Annexes B to K specify equipment requirements, Annexes L to M specify measurement equipment calibration and mechanical property testing requirements, and Annexes N to P provides information on polished rod liners, typical examples of sucker rod discontinuities, and pumping systems.
Key Updates
The 28th edition of API Spec 11B includes many key updates, including:
(1)New requirements for polished rod liners: These new requirements are designed to improve the performance and reliability of polished rod liners.
(2)Updates to the mechanical property testing requirements: These updates are designed to ensure that rods meet or exceed the required strength and durability.
(3)New annexes: The new annexes provide additional information on a variety of topics, including measurement equipment calibration, mechanical property testing, and polished rod liners.
Impact on the Sucker Rod Industry
The updates to API Spec 11B are expected to have a significant impact on the industry. The new requirements for polished rod liners, in particular, are expected to lead to improved performance and reliability of rod pumping systems.
Conclusion
